Myrcene
/MUR-seen/
The most abundant terpene in most cannabis strains. Produces an earthy, musky aroma. Proposed to enhance cannabinoid absorption and contribute to sedating effects.
In Depth
Myrcene constitutes up to 65% of the terpene content in some cannabis strains. It is also found in hops, mangoes, and lemongrass. The popular claim that eating mangoes before cannabis use enhances effects is based on myrcene's proposed ability to increase blood-brain barrier permeability to cannabinoids — though this has not been rigorously tested in humans. Myrcene has demonstrated sedative, analgesic, and anti-inflammatory properties in animal studies. The "indica = sedating" stereotype may partly reflect high myrcene content in indica-dominant strains.

Decarboxylation
The chemical process by which a carboxyl group (COOH) is removed from a molecule, releasing CO₂. Converts inactive cannabinoid acids (THCA, CBDA) into their active forms (THC, CBD).
THCA (Tetrahydrocannabinolic Acid)
The acidic, non-psychoactive precursor to THC found in raw, unheated cannabis. Converted to THC through decarboxylation.
CBDA (Cannabidiolic Acid)
The acidic precursor to CBD found in raw cannabis. Converted to CBD through decarboxylation.
Lipophilicity
The tendency of a molecule to dissolve in fats, oils, and non-polar solvents rather than water. Cannabinoids are highly lipophilic.
Limonene
A citrus-scented terpene found in cannabis and citrus fruits. Associated with anxiolytic and antidepressant effects in preclinical studies.
